Mahendra Institute is institute that provide coaching for preparation of government job like IBPS, SSC, RBI clerk e.t.c.Their teachers are good but they teach on which syllabus are not enough for current exam level so I do not recommend that you go there and study because day by day competition going to be very tough.Their study material also at average level and I think it is only for lower level exam.Their academic program and administration is satisfactory but again I do not recommend this institute for upper tier exam
